第 1 阶段：虚拟实训台，项目 2、3 的示例跑通

Browse Source 
- 实训台状态由服务器统一保存：滑块和开关设定传感器读数，推给学生程序；
  学生程序控制的灯、继电器、LED 屏回写到实训台
- 网页按教材实训台布局图绘制实训台，传感器卡片上直接调节环境
- 新控件：CheckBox、RadioButton（事件顺序与 WinForms 一致），Lamp、Alarm
- 设备类库：串口未打开时控制无效，与实物一致
- 修正：列表属性序列化时数字被转成字符串
- 示例：项目 2 任务 2–3、项目 3 任务 1–2；网址参数 ?sample= 打开指定示例
- 测试：实训台单元测试，项目 2、3 的端到端测试
